Rekey or Replace? What to Do With Your Locks After Moving in Baltimore County

Rekeying a lock means a skilled locksmith disassembles the lock cylinder and rearranges the internal pins so that the old keys no longer work. Your existing hardware stays in place — only the combination of pins changes. This is the go-to solution when your locks are in good mechanical condition but you simply want to invalidate any keys that may be floating around. For most standard door knob locks and deadbolts in decent shape, rekeying is the faster and more straightforward service.

Replacing a lock means removing the entire hardware assembly and installing a new one. This makes sense when the existing lock is worn, damaged, or a low-security model that doesn't meet your needs. It's also the right move when you want to upgrade — say, from a basic door knob lock to a heavy-duty mortise lock, which offers significantly stronger resistance to forced entry. A mortise lock fits into a deep rectangular pocket cut into the door edge, giving it far more contact with the door frame than a surface-mounted cylinder. Many Baltimore County homeowners upgrading from builder-grade hardware find that installing a quality mortise lock is the single biggest security improvement they can make on move-in day.

If the locks on your new home are relatively new, function smoothly, and are a reputable brand like Schlage or Kwikset, rekeying is almost always the smarter first step. It achieves the core security goal — making every previous key useless — without the expense or time of a full hardware swap. A professional locksmith can typically rekey every exterior lock on a standard Baltimore County home in a single visit, and can even key them all to one master key so you're not juggling a different key for every door.

Rekeying also makes sense if you're a landlord turning over a rental property in areas like Pikesville or Catonsville, or if you've recently gone through a situation like losing a key or ending a relationship where someone had access. The bottom line: if the hardware is sound, rekeying is efficient and effective. If you're also wondering what to do if locked out of your house on moving day — which happens when keys get packed by accident or transferred before the rekey is done — our team can handle the lockout and the rekey in the same visit.

There are clear situations where replacing the lock is the better investment. If the door knob lock or deadbolt wobbles, the key sticks, the latch doesn't seat properly, or you can see visible wear on the strike plate, rekeying a compromised lock only gives you the illusion of security. Damaged hardware should be replaced outright. Similarly, if your home has older skeleton-key-style locks or thin privacy knobs on exterior doors — which is not uncommon in some of the older housing stock found near areas like Woodlawn or Pikesville — replacement is the responsible choice.

This is also the right moment to consider a mortise lock installation on your front door. Unlike a standard cylindrical lock, a mortise lock integrates the latch, deadbolt, and often a security bar into a single robust unit recessed into the door itself. They are substantially harder to kick in or pick and are the standard on high-security residential and commercial locksmith applications alike. If you're moving into a home with a solid wood or steel door, it's almost certainly compatible with a mortise lock upgrade. Ask our team during your visit — we carry and install quality hardware and can show you the options that fit your door and your priorities.

Moving day chaos is a perfect setup for a lockout. Keys get handed off at closing and then accidentally packed in a box, a family member locks the door out of habit before everyone is inside, or the new key simply doesn't work because the lock has never been properly aligned. Knowing what to do if you get locked out of your house before it happens puts you in a much calmer position when it does. First, check every ground-floor window and any secondary entry points — not to force anything, but to confirm whether any unlocked access already exists. Check with neighbors who may have been given a spare by the previous owner. And if you're truly locked out with no other options, call a professional rather than attempting anything that could damage the door, the frame, or the lock itself.
